Hello, I built gcc-5.3.0 on ubuntu 14.04 and the build succeeded (with g++-4.8.4, no multilib). Then I ran the test suit with `make -k check` and this went on for 4 hours and finally completed with ... === libatomic Summary === # of expected passes 54 make[4]: Leaving directory `/home/oar/Projects/Cpp/gcc/gcc_5.3.0_obj/x86_64-unknown-linux-gnu/libatomic/testsuite' make[3]: Leaving directory `/home/oar/Projects/Cpp/gcc/gcc_5.3.0_obj/x86_64-unknown-linux-gnu/libatomic/testsuite' make[3]: Entering directory `/home/oar/Projects/Cpp/gcc/gcc_5.3.0_obj/x86_64-unknown-linux-gnu/libatomic' true DO=all multi-do # make make[3]: Leaving directory `/home/oar/Projects/Cpp/gcc/gcc_5.3.0_obj/x86_64-unknown-linux-gnu/libatomic' make[2]: Leaving directory `/home/oar/Projects/Cpp/gcc/gcc_5.3.0_obj/x86_64-unknown-linux-gnu/libatomic' make[1]: Leaving directory `/home/oar/Projects/Cpp/gcc/gcc_5.3.0_obj' make: *** [do-check] Error 2 make: Target `check' not remade because of errors. I could not find any .log or .sum files. Running src_directory/contrib/test_summary produced empty output. What is going on? Surely some log files will be written while the tests are being run. Where are these? Thanks Michael Meyer
